The work of Father Anscar Chupungco on the Cultural Adaptation of The Liturgy is an indispensable work at this time when each country, and especially the ‘new’ nations of the developing world, attempt to experiment with the adaptation (inculturation) of the liturgy in their own cultures. Without scientific understanding of the history and tradition, such attempts are doomed to either caprice or defeat. This book ought to become the manual of any adaptation.
